    How long before we see that headline? Smile

    Seriously? There was plenty of speculation, rumour then teaser ads before the 5D II. Any rumours of a 1D IV soon?

    Are Canon going to refresh the 1 Series this year? I'm not that up on the Photokina Trade Show - is there a traditional day for the big / surprise announcements?

    What size sensor would they put in a 1D Mk IV? Will there even be a 1D Mk IV or could the 1 series go totally full-frame?

    The 1Ds IV could be a 5D2 in a pro body, but what about the regular 1D IV?

    you mean mean person!
    If canon stick with the idea of video in their DSLRs then I would expect and improvement over their already impressive 5DM2 -- with a crop sensor they could try for a much faster shutter speed - maybe even as far as boosting the speed to allow for a slowmotion replay to be created.
    I think Canon will keep it crop sensor since many (wildlife/sports) still prefer the faster shutter speeds - although this is greatly dependent on their plans - if they can boost fullframe shutter speed and buffer size whilst retaining quality then many would move to full frame for the additional space if the speed was up to standard.

    I'm not sure they would up the video frame rate. Remember the video mode doesn't record the whole output from the sensor - on the 5D2 it uses 1920 x 1080 pixels -(1080p HD)

    The chip that encodes that video to a H.264 Quicktime file is probably going as fast as is practical.

    true - but canon are well known for hobbling lower end cameras - even though the 5DM2 is midrange its still hobbled (focusing points for example) -- though the upgraded 1D series could take resolution of video much higher.
    I would expect the crop sensor to also follow in the footsteps of the 50D with a big MP increase - they just can't (marketing) allow a lower end camera to have more MP - since we all know only MP sell cameras Wink. I just hope that with the 1D series the boost of MP and thus noise reduction won't lead to loss of sharpness in shots! Even though 50D shots are now showing good levels of sharpness one can't help but wonder how much sharper they would have been without the MP boost - the other problem is that it makes it harder for lesser photographers to get tacksharp results - skill with the tool has to be spot on

    On the subject of the video, the top resolution for HDTV is 1080p. That's as good as it gets with a top of the range plasma and a Blu-Ray player. A lot of the displays in people's homes only support 720p, it was only really this year that full HD panels became affordable.

    In theory they could go higher so that you could cherry pick video frames to save a stills for printing etc. I don't think they will though.

    Feb/March 2009...... maybe. PMA is in Las Vegas in March 2009. The 1Ds III is not due for replacement until 2010 on Canon's 3-year cycle for 1 and 5 series cameras.

    But I doubt they can afford to wait that long.

    except that was the reason Canon went for HD resolution - to allow the press to pick stills for print and video for the web - boosting resolution would seem to be a good move to improve the stills capture feature - two for one Smile

    I read somewhere that Canon research and development was forced by Canon marketing into boosting MP over other features - and since marketing is in control of production and research these days I think MP will remain high on priorities - least for Canon's current line of thinking

    But there is no standard for video above 1080 at present, so any higher resolution would be useless for that purpose.

    I am not aware that Canon are touting the video function on the 5D II as being for cherry-picking of frames for stills, although obviously that can be done. The 2-megapixel frames will be fine for the web and even for standard prints or indeed pictures up to 6"x4" in magazines (at 300ppi).

    Hi all lads, I have my canon EOS1D mark 2 N , I have beautiful 20in by 30in print showing good details and pin sharp, its 8.5MP!!!!!!!!!!!!!!

    The lens I use was 28-70 F2.8 L

    Would that 21MP be enough for 40in by 60in with cheap lens?????????????

    Who knows lol

    30"x20" from 8.5Mp = 119 ppi

    Using the same quality you would get 47"x32" from 21.1 MP.

    No.

    No matter how many pixels you can get out of a camera the lens is the ultimate factor on quality and a high end camera will show up the weaknesses in the lenses.

    I don't think the 28-70L was a cheap lens in its day?

    But Eric makes a fair point: the higher the sensor's resolution the more demanding it will be on any lenses.

    1DMIV, yes it will probably come in due course, Mark 4 to differentiate with Mark 3 - hence new AF system, marginally higher frame rate and MPs, the ground breaker should be low light capabilitiy, and more controversially I suspect real Quality Video.

    This is probably where the boundries of still and motion will start to come together.

    My view though is that they need to upgrade older and introduce new lenses to their portfolio.
